From 3dd654bfdf8905d0acb6f6231b5e736d2b0d4bc6 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Mon, 28 Apr 2008 12:41:36 +0100 Subject: [MIPS] ATA: Rename routerboard 500 to 532 The platform is actually named routerboard 532 so let's call it this. This patch only rename files, Kconfig and C symbols; no functional changes.
